一种基于多点测距信息的复合制导方法

分析探讨了一种用于提高弹道式导弹对目标命中精度的复合制导方案，提出了通过进行多点测距，利用状态转移矩阵方法，来估计导弹落点偏差和末修级起控点飞行状态参数，然后再按照需要的速度进行末修级导引控制的复合制导方案，并通过仿真计算分析论证了该方法的可行性。

An Approach for Composite Guidance Based on theInformation of Multipoint Measuring-Range

Abstract In this paper , an approach for composite guidance to be used to improve the impacting ?target precision of ballistic missile is described. The composite guidance scheme is put forward in the paper which includes the following steps: firstly , to measure the range of a couple of points ; next . to estimate the impact deviation of the mi-ssile and the flight state parameters at the beginning of control in terminal velocity adjustment by using state transition matrix method ; finally, to implement the guidance and control based on required velocity. Its correctness is proved by simulative analysis.
